NAEV 0.4.0 review

NAEV Items [more shots]

NAEV 0.4.0 is out, a game of the space trading and combat simulator genre, inspired by the non-free Escape Velocity. Win32/lin32/lin64/mac binaries are available here.

The new version has parts of the user interface changed and is better accessible, for example through in-game gui keybind editing. Three aspects of NAEV show that usability is a priority: 1) the tutorial is informative without overwhelming too much 2) most combats can be evaded through the run away-tactic (this might be unintended, but definitely liked by me). 3) The automatic jump system, that allows consecutive jumps to systems without having to manually repeat standard maneuvers gives much relief to the player.

The changelog also lists better-looking visuals as well as new sounds and music tracks. As a bonus, all the art in the game is licensed under Debian-friendly licenses. [license.txt: audio, visuals]

Gameplay

Wingmen fighters in action

In NAEV the player starts with a small trading ship and needs to earn money to buy new vessels and equipment. Trading or patrolling missions are the key to income. Though I'm no fan of playing lots of similar missions in a row, I did feel satisfaction, when discovering the most effective way to earn money with them: play patrolling missions and a lot of them at the same time.

Along with the repetitive, generated tasks, there are some original missions of different difficulties that allow the plot to progress and/or provide alternative methods of earning credits. They alone are reason enough to give NAEV a spin. The developers want to include more and more story missions, so contact them via IRC or mailing list if you're up to some sci-fi 'quest' writing! :)

A third (or is it fourth?) method of increasing wealth is observing prices and buying where prices are low and selling where products are expensive. However, there is not much of an economical simulation implemented in NAEV yet, so I wouldn't recommend this path for now.

Yet another battle

Scout ships, fighters and battle-cruisers are available in the shipyards of NAEV, different kinds of energy and missile weapons can be bought, various upgrades can be installed. The brainless method of costlier=better didn't work for me, I had to balance the effects and firepower against speed an maneuverability. Running away is more enjoyable to me than fighting and waiting ten seconds for my ship to turn.

The coolest item in the game is the fighter bay. It allows to host small allied ships in your cruiser. After 'shooting' them into space, they will attack enemies and can be controlled with a few simple commands. Place two is occupied by the afterburners, which will give a temporary speed boost at the price of having the view shaken.

Interviews

Next, two questions for the current top 5 NAEV contributors (and two extra ones for the lead dev):

Q1: What is your role in NAEV development?

bobbens: I am the lead developer of naev.

Deiz: I do a bit of everything, as required.

Done graphics, sound, missions, etc., but most of my time has been spent on making the sprites look nice and getting the game to a fairly balanced state.

For sound I mostly hunted things down and vocoded a few sounds to get the results I wanted. For graphics, most of the ship models are sourced from Vega Strike, many of the outfit graphics are based on models by Joss that I've heavily hacked up.

brtzsnr: I coded a couple of features that NEAV lacked (one of them is the faction disks), now I'm working on 3d-models and sometimes I fix bugs. I wish I had the time to implement more complex features.

stephank: I wrote some code to save configuration. It was unable to at the time.

BTAxis: I've provided some game content (two missions and half a dozen systems so far). That is the extent of my active role in NAEV's development. However, I also occasionally put forward proposals for new or improved game mechanics on the project mailing list, and if I can make them convincing enough and/or talk bobbens into seeing things my way, they may one day find their way into the actual game. I enjoy doing that. Thinking up game mechanics, making them work in my head and fitting them into a bigger picture is fun for me.

Q2: What do you want the game to become in the future?

bobbens: I want the game to be as good as the memories of my childhood playing original EV made it to be.

Deiz: Ultimately I'd like to see NAEV be appealing to a broader audience. At present if you're not somewhat familiar with the Escape Velocity/Elite/Freelancer/etc genre there's not too much to grab your attention.

brtzsnr: I hope NAEV to become more RPG-like (have a crew with different skills tree, say one engineer, one pilot, one commander, etc). Also I want more non-linear/intricate stories.

stephank: I played a lot of Escape Velocity, so that's why I got interested in NAEV. It looks and feels a lot like EV right now, but it looks like the (active) developers are mixing in interesting features from other games in the same genre, and even innovating. I would like them to surprise me, more so than me influencing them. :)

BTAxis: I already mentioned the proposals I wrote up. They're essentially the answer to this question, or at least they're the story so far. But if I'd have to explain it in two words, I'd say that I want naev to be a space exploration game that offers a high degree of interactivity while at the same time providing and engrossing and believable world for the player. That is not an easy goal to meet. Most space games that I know of sacrifice one aspect to pursue another, and in the end NAEV may have to as well. But at this point in time, I believe it's doable, and I hope to be part of making it happen. [For more information check out the proposals on NAEV's mailing list]

Q3: What made you start the project?

bobbens: I started the project about 6 years ago by myself when I realized that there was no game like EV (which I had played extremely intensively as a kid) on linux. EV also had major gameplay flaws that should have been worked around.

Since I had no projects at the time I started out with the ambitious NAEV, which over the years has slowly been taking shape and was released recently (one year ago) to the general public.

As of 0.4.0 I'm starting to be pretty impressed by the results.

Q4: What do you think of Star Control II (The Ur-Quan Masters) as an example of a EV-like GNU/Linux game?

bobbens: I only played Star Control II after someone mentioned it to me about 6 months ago. It does seem to have a lot of EV features, but it seems to lose a bit the fast paced-ness of EV and customizeability of the ships. However it does have other great features that EV lacks like the zooming in systems and the dialog use.

It's good to find good features in other games and use them for inspiration in NAEV, it's evolved enough that it no longer is an EV clone. It also takes from all over while trying to keep itself unique.

OpenMW interview with Nicolay Korslund

Early OpenMW GUI implementation

OpenMW is a re-implementation of the (non-free) TES3 Morrowind game engine, written in the D programming language. The engine makes use of OGRE and other open source libraries, features an own scripting language called "Monster" and the latest release has the version number 0.6.

Out of curiosity, I asked Nicolay Korslund (the lead developer) one year ago what his motivation for writing OpenMW was. Later I decided to ask some more and now you can finally read the interview, in which Nicolay tells us about Git, OpenMW's development and whether or not to expect original games as a result of the OpenMW project.

The interview

Q1: What is your motivation for writing OpenMW?

Initially the project was started a few years ago (somewhere around 2004-2005, don't remember exactly), out from desire to improve a game I loved and from frustration with bugs and issues that made it less fun than it could be. Having been a programmer for about a decade, I felt that most of the bugs were unnecessary and could easily have been fixed if Bethesda has devoted the resources to it. I started getting that curious 'I could do this better myself' feeling, that you sometimes get when you've been doing a craft for years and aren't satisfied with someone elses work. (Not that I think Bethesdas coding is shoddy in any way, they're a company with limited resources like any company, and sometimes you just don't have the money to improve thing ad infinitum even though you would like to.)

To keep up (or even start) a big project such as OpenMW, though, you'll usually need more than just one big motivation to drive you and keep you going. For example, I knew from the outset that this project was something that others would get excited about, and that's a big motivating factor. The amount of positive feedback I've gotten on OpenMW since release has been pretty stunning, and it really helps to know that what you're making will affect others in a positive way. I had always wanted to contribute to open source software, but so far hadn't found any project I burned for, and none of my own projects ever made it to the point of release.

Another motivation you'll need of course is the joy of working on it - it's a hobby after all. I love programming, I love improving things, and I love reverse engineering file formats. Thee big pluses when you're doing a reimplementation. It also forces you to learn new skills - I've always wanted to learn more game development, such as using a 'modern' 3D engine, but I never had any real motivation to do it before I started OpenMW. On top of all that I had just fell in love with the D programming language, which blew me away to the point of abandoning C++ literally over night. D had (and still has, to some degree) a desperate need for more attention getting projects, and I wanted to help with that. I knew there would be challenges with using such a new language, but I was determined to show that none of them were show stoppers.

Q2: Are other people involved in OpenMW or Monster?

Yes, quite a few really. I started a mailing list for OpenMW about a year ago, after initially getting very positive feedback on the project. The list now counts over 130 members, and even more pay attention to the project through various forums. Only a very small fraction of those have contributed code of course, but many contribute other things like testing, knowledge about the file formats/mods, or simply through feedback and ideas. For Monster I've intentionally run a somewhat lower profile, but there are a few of early-adopter-type developers who are using it in their own engines. If things go as planned though, the two projects will become much more intertwined in the future, and I hope that Monster can contribute a lot to OpenMW (and make my job as lead developer a lot easier.)

Q3: How did you find those people? Or was it them who found you?

I've done very little 'advertising' for my projects - I think I posted about OpenMW on exactly one forum (the OGRE forum), the rest took care of itself. I had to create the mailing list simply because I couldn't keep track of all the individual conversations any longer.

Q4: Are you going to make OpenMW usable with non-Morrowind content, so that new games can base on it? If yes, will you make such a game?

It's very possible that the project will spawn an engine that's usable for other games, but we don't have any specific plans for that right now. Although we are on friendly terms with another project that uses much of the same technology, called DungeonHack. It's very likely that our two engines will share some code in the future.

Even though we're not working on making a generic game engine, it will likely be possible to make much more extensive Total Conversion mods for OpenMW than for the original Morrowind engine. And the scripting features we're planning will let you bend the rules to the point where you would probably not consider it to be the same game anymore. Personally however I have very little talent for game creation (except for the coding part), so I don't think I'll be behind any of those mods myself.

Q5: You've picked OGRE as OpenMW's 3D engine. What about the alternatives (Irrlicht, jMonkeyEngine, Crystal Space, writing an own 3D engine...)?

I think probably all those (and many others) would have been good choices, except the last one. Writing a new engine and getting it to a point where it could compete with OGRE et al. would have taken years, and IMO it's usually a complete waste of time unless you're doing something really unique with it. There are so many good and free off-the-shelf alternatives out there (too many already...), and if you need some feature that they don't provide you can usually add it in yourself in 1/100th of the time it takes you to write a new engine from scratch.

Q6: You recently switched to Git from SVN. What motivated the switch?

Popular demand :) But after trying out Git (and taking the time to understand how it works), I fell completely in love with it myself. SVN is now ancient technology as far as I'm concerned. And with git-svn, Git is even a better Subversion client that Subversion is. However since it's so easy to integrate the two, we are keeping the SVN repositories on-line for the foreseeable future, and existing SVN users don't really need to change anything. I know it takes a real geek to obsess this much over a version control system, but that's how it is :)

Interview: Stephen Carlyle-Smith aka Me_Programmer

In the second Free Gamer interview - over 2 years since the first with grumbel - serial Free game developer Steven Carlyle-Smith (UK) aka Me_Programmer Games aka Steve16384 was kind enough to take the time to reply in detail to my questions about his development activities.

Steve has created a plethora of Free games over the years. Whilst they have struggled to gain mindshare - usually he moves on at speed to new projects before completing others - there's a lot of content to peruse and I thought his experiences were more than worth tapping for advise to budding game developers. He has created all his games with little or no community help other than occasionally reusing resources from other projects. He also maintains blog on his development efforts which is often witty.

You can ask questions / get support / give feedback for Steve's games in the new FreeGameDev forum for Me_Programmer Games. There you can also find an exhaustive list of his playable game projects, including several not mentioned here.

He is also responsible for coding/creating the site Online Game Planner - which he uses to host his projects - which is a fairly new portal for organizing multiplayer gaming sessions.

The game that originally got my attention was Laser Tactics - previously called Nuclear Graveyard, which he talks about later in the interview. So, without further ado...

The Interview

Q. Please introduce yourself...

I'm a 30-something professional applications programmer, amateur games programmer, married with one child and another on the way.

Q. What do you do for a living?

I work for a small company writing software for businesses. Everything from web applications, social networking sites, VB apps, web filters, stock control software, networking tools, and the odd game. Whatever people will pay for!

Q. What notable games have you created?

I don't think any qualify as notable -- editor is impressed with the humility, some of the games are good they just haven't hit the right public spot yet! -- but these are probably my best:-

Xenogeddon (home)

This is a simple FPS based on Space Hulk, but I'm very pleased at how the graphics turned out. I didn't do any of the models, but overall it captures the Space Hulk imagary quite well. It is small and simple however, and needs a lot more scenery and features adding to keep the player's interest.

Laser Tactics (home)

The less said about the graphics the better, but this is my attempt at making a pseudo-realtime verson of Laser Squad and have tried to recreate the original graphics in 3D. It uses what I think is a unique system where both side's "action points" are replenished in real time which can make for interesting gameplay. I'm also particularly pleased with the AI as well. The overall presentation could do with a damn good polishing though.

Island Commander (home)

This is my most recent game and I'm still working on it, but it's fully playable and I enjoy playing it. I've always liked strategy games, and this one is a simple RTS/RTT where the player builds units and then watches them do battle. I'm interested in games where you only have indirect control. I've got loads of ideas yet to implement, like different races, more unit types, and maybe a better name!

Q. Of your game projects, which is your favourite?

At the moment it's Island Commander, because it's my newest and I still enjoy playing it. I'm probably most proud of Xenogeddon though, in that if someone asked me to show them one of my games, that would be the one.

Q. Excluding your own, what is your favourite open source game?

I don't spend that much time playing games, but the one I used to play the most is Tremulous, probably because it's multi-player with a big player-base. I'm crap at it though.

Q. What games do you play at the moment, FLOSS or commercial?

Definitely FLOSS, as I haven't bought a game since X-Com for the Amiga! My home PC isn't up to playing modern games and I don't have time anyway. I'd much rather be programming games than playing them. When I do play games, it's usually simple but addictive Flash-type games. And if they're very simple, I then have a go at writing my own version.

Q. How did you get into games programming?

Way back in 1984, my dad bought a ZX Spectrum, and the book "First Steps with your Spectrum" to go with it. Ever since then I've been programming, for the Spectrum, Amiga and then PC. I like to think my games have improved since then.

Q. What are your best games programming tips?

Re-use your own code as often as possible. Have something playable as quickly as possible. And use descriptive var/function names. I don't agree with people who dislike verbose var/function names; if you're sharing code with others (or coming back to your own project after a 6 month gap) you need as much description as possible. With tools like code-completion, long names aren't a problem.

Q. What draws you to open source, what is your Free software philosophy?

I particularly like the way that we all provide each other with programming help and actual source code, which enables everyone to learn and produce software much faster than they would be able to otherwise. It's a shame that in the corporate world, when somebody learns something, it's top secret and usually patented. Just think how advanced technology (not just software) might be if everyone shared their knowledge and skills with everyone else.

Q. What are the things to avoid, the things that make FLOSS game
development fail?

The biggest problem is not getting something playable as quickly as possible. Whether its a one-man project or bigger, people soon get bored of discussing and planning everything to death. You need to show yourself and everyone that you are actually doing something practical that is actually possible and progress is being made. There are a million "Status: 1-Planning" projects on Sourceforge as a testament to this.

Q. If you could take one abandoned FLOSS game and restore it's
development (excluding your own titles!) which would it be?

I don't really know any off the top of my head. I sometimes browse Sourceforge to see if there's anything I can help with, but I usually end up with ideas and inspiration to write a game of my own! Unfortunately, trying to understand someone else's source code and designs (especially the larger ones) is often harder than just writing my own project.

Q. What are your future game development plans and which of your games
do you hope to see come to fruition in the near future?

My dream is to have a game (and more importantly, a community) as popular as, say, Starcraft. This is my ultimate (and obviously unattainable) ambition, but if one of my games can get a thousandth of the popularity of that, then I'll be more than pleased!

Steve's Other Game Projects

You can ask questions / get support / give feedback for Steve's games in the new FreeGameDev forum for Me_Programmer Games. There you can also find an exhaustive list of his playable game projects, including several not mentioned here.

Danger Man




HoloRacer

Danger Man (home)

This is my contribution to the saturated market of platformers. It's reasonably complete, but requires more levels designing and it's own set of graphics. It has a few good features though, like different weapons.

Metal Glove Solid (home)

This is a playable but limited version of Gauntlet. The advantage of having this in my repotoire is that if I want to make any other top-down 2D game, I can just start with this. I do that with a lot of my games, meaning I can usually knock something up very quickly. I just need to improve the graphics and create more levels.

HoloRacer (home)

I'm quite pleased with this one, and I sometimes go back and have a quick game. I just wanted to write the fastest racer that I could, and it was my first game using OpenGL. It's deliberately quite simple (in gameplay and graphics) but fun in short bursts. I seem to remember that when I uploaded it to Sourceforge, it got about 200 downloads on the first day. They'v trailed off a bit since then!

Realtime Chaos (home)

This is a remake of "Chaos - The Battle of Wizards" for the Spectrum, where wizards do battle with various spells, but converted into an RTS. I've written countless version of Chaos over the years, but this is by far the least-worst. The only drawback is that it has no AI, so you need at least one other player and a LAN to play a game.

Simwar (home)

This is an RTS in the style of C&C. It's quite simple, and also multi-player/LAN only, but is designed to be quick and fun to play. It has some features like proper line-of-sight (unlike just fog-of-war), so you can only see the enemy if you have a clear view. Prizes for guessing which game the soldier sprites came from!

GTA-MUD (home)

As the name says, this is a MUD. I liked the contemporary setting of GTA, and thought a MUD in the same setting would be a good idea, where you could do anything in a modern-day realistic setting rather than either medeival fantasy or futuristic. It's quite small, but gets about 5 logins a day. It's also quite "adult" in some sections, just like GTA.

Online Game Planner (home)

This is a website I produced. I think this was inspired by me trying to get more players on at the same time on GTA-MUD. The premise is simple - you select an online games that you play, and then organise a session by date and time. Everyone else who has also marked that game as one they play then gets informed of the date and time, so everyone plays the game at the same time. It also hosta a few of my simple applet games. I think I should rename it "MultiplayerGamePlanner".

The Last Word

I'd really like to see Steve polish some of his older games a bit more and be more astute with advertising them. Some of them are very hard to come by unless you go through his blog, so posting announcements/showcase/help-wanted threads in the appropriate forums (starting with the FreeGameDev forums) should increase their visibility.

Xenogeddon looks full of potential and it'd be good to see what people make of it. I don't have functional 3D so couldn't try it myself yet.

Metal Glove Solid could become a popular game if he worked on performance (it was unplayably slow on my graphically-unaccelerated 2ghz laptop) as well as used the better graphics available in the Gauntlet Resurrection thread from the FreeGameDev ideas forum.

There's a lot of projects that he didn't mention because he feels they're not complete enough, e.g. this Shadowfire remake. It makes me curious to know if there's a complete list of Steve's projects anywhere! See update!

Sometimes the life of a Free game developer can feel a bit lonely because of the lack of exposure. Hopefully some of you will go away and try his games and, even if you don't end up playing them for long, at least give some decent feedback so he can work to make them better and increase player retention.

Update: Steve has posted a complete list in the forum. Two games he has made that he didn't mention in the interview but are worthwhile projects are Passenger and Last Remaining. I think he needs a bit of modelling help to really realise the potential of Last Remaining.

English transcription of "Hobby Game Development" (neues, 3sat)

Narrator: On first sight it looks like the commercial online role-playing game Ultima Online. On the second the viewer might spot one or another change. Maybe even something special, which doesn't even exist in the original game.

This game is named Iris 2, built on top of Ultima Online and is freely available online. It was developed by hobby game developers.

It's their hobby, just like others knit pullovers in the evening. Florian Fischer and Iwan Gabovitch develop games in their free time. What's the thrill of developing games on your own?

Florian: It's just fun to be creative and to express this creativity. Games are super for that.

Iwan: First I stopped playing commercial games and started searching for new, interesting games. I found many freeware games and then came across the open source scene, where also games get developed, where
it's easy to contribute, without having to get involved too much.

Narrator: Most developers are not professionals but they have lots of potential and ideas, which they want to share and to put into practice with others.

Free software is being used, which is available gratis online. For example to create graphics of special effects.

For the 3D visualization, Florian works with OGRE. OGRE is open source software, which can be copied, distributed and used without limitation. Working with free software excites the developers.

Florian: Others can download our code, can compile games on their own, can try own things and can improve the programm. The principle of open source is nice: I give something and, as I use open source tools, I also take something.

Narrator: Usually each developer works seperately on his computer but once a year the hobby developers meet live.

The event Dusmania was initiated so that developers could exchange experience, but of course there has to be some actual development too. In nine hours, they had to develop a game. The group of Iwan and Florian created "lalalove", a game in which sounds have to be generated to make people happy.

Iwan was responsible for the graphics in lalalove. First he sketches the images, before layouting them on the PC.

Somebody who invests so much love and free time into game development could work for commercial game producers, but this doesn't interest the community.

Florian: We don't have to follow any rules, we can implement every idea and we can throw it out too. We can be as creative as we want to be and this is fun. We can create prototypes of games and then say "we like this game principle" or maybe someone else in the community likes it and develops it thurther. I find this freedom fascinating.

Narrator: One who wants to experience developing games on his/her own, finds a lot of tips on the web. Beginners are also able to get into the scene easily.

Free Gamer is an online community for hobby game developers. It consists of a blog, a forum and a wiki. The forum is for discussions. On the wiki articles can be published and freely edited. For example there is a list of open source 3D game engines, which everyone can use for his own games.

If someone prefers to play rather than develop, won't be disappointed. Games of all sorts are available on the net. For example the cute SuperTuxKart. Instead of Mario, a penguin drives against the tree.

End of transcription. Please not that all text by the Narrator is not freely licensed and it's copyright is owned by 3sat.

Please note that simplification and generalization are unavoidable if you want to squeeze a topic into four minutes. There are of course people who are interested in commercial application of open source and there are open source game developers who would like to work in non-free, commercial game developer companies.

qubodup and SiENcE on German TV

Left to right: SiENcE, qubodup

Update: The video can be viewed on YouTube (the part about us starts at 18 seconds).

Hello friends.

Today's post is just a quickie: I (involved in some stuff) and SiENcE (involved in both Iris 2 and OGRE) were interviewed by Cornelia Rettig for 3sat's neues (in German). We talk about open source and hobby game development, visit the Free Gamer blog, the FreeGameDev forum and wiki and show Iris 2, OGRE and SuperTuxKart.

I am ever so excited.

If I understand correctly, you are able to watch the full show inside a time frame of two weeks. Here's a direct link to a asx (windows media player steam file, Kaffeine was able to play it for me.)

You can read these news in the Iris 2 blog too! Also there's an article on 3sat's homepage and you can read an auto-translated English version (using google tools).

In case there's interest in an English version of a transcript of the show, I guess I could do it...... just tell so via the contact link at the top of the blog or via posting a comment in the blog or in the forum. A longer post by me is coming up soon by the way. :)

One step closer to world domi... ah, that joke is getting weak. :p

Interview: Ingo Ruhnke aka Grumbel

In the first of a new wave of Free Gamer content, Ingo Ruhnke aka Grumbel and one of the most prolific open source game developers around has kindly taken the time to do an interview.

Please note that Ingo's first language is not English, and I've not modified his answers in any way other than to sanitize links. I have made a few notes on his answers at the end of the interview. Many thanks to Ingo for taking time to answer my questions, especially in so much detail - much more than I could have hoped for! :-)

Just in case you left your brain at home today, the questions are bold and prefaced with a Q - and the answers, er, not bold with no Q.

Q. In my best Cilla Black accent, "What's yer name an' where d'ya come from?"

My Name is Ingo Ruhnke in the real world, on IRC and web forums I use to call myself Grumbel. I am coming from good old Germany from a town called Bielefeld:

http://en.wikipedia.org/wiki/Bielefeld_Conspiracy

Q. And what do you do for a living?

I am going to end my studies soon, not yet sure what I will do after that, I thought a bit about turning into the independent game business, but not sure if I will actually do it in the end.

Q. What is your favourite open source game(s)?

Adonthell, since it happens to be one of the very few open source games that actually has story, characters and dialog, it also happens to have the best music of any open source games rivaling even that of many commercial titles. The gameplay of the game is very basic, but story, characters and stuff are just so good that its simply not an issue. Its not the longest game around, but the most interesting one.

Q. What is your favourite commercial game(s)?

That would be Another World and The Longest Journey.

Another World because it was and still is absolutely revolutionary in so many aspects. Its a very short game, but one that basically never repeats, every moment in it is uniq, the story, even so told without a word is absolutely stunning and the polygon based 2D graphic was something very different then everything else at its time. Its a game that simply lacks what makes video games look like video games and instead turns them into an interactive experience. And as if that wouldn't be already enough, its also a game that got created from start to finish by only a single person.

The Longest Journey on the other side is much more a classical adventure game, but one of the best. It improved on what LucasArts did in terms of interface and added an epic sci-fi/fantasy story into the mix like there is no other. I like games that feature interesting characters and worlds and The Longest Journey simply has tons of both.

Q. What games do you play at the moment, FLOSS or commercial?

At the moment not much, I don't yet own any of the next generation
consoles (still waiting for a price cut on the XBox360) and there
simply aren't much more games coming out for the current generation.
So I am kind of stuck there. My PC also happens to be not in the shape
any more for commercial PC games and that Vista Beta I am running
beside my Linux isn't exactly in the best shape either. However I
recently replayed AstroBoy Omega factor on the GBA, since thats my
favorite game for that machine and I also plan to have a deeper look
into my linux version of X2 soon.

In terms of FLOSS I don't really play much of those at all, I enjoyed
Adonthell a lot, had some fun with Neverball, but beside that I am not
interesting in most of the games

Q. What open source games have you worked on, preferrably in chronological order?

Lets see if I can get that figured out without forgetting anything:

In the very beginning I did some C64 Basic and QBasic applications,
most playable was a simple clone of that motorcycle game of the Tron
movie, another thing was a labyrinth/dungeon game, but that never went
anywhere and didn't got finished. All that stuff is available on the
net, but not very interesting for most people I guess:

After those I moved on to C++ and coded Retriever, it was meant to be
an adventure game and written under DOS with DJGPP and Allegro, it
never went beyond a little demo in which you could walk through a few
screen, but I am currently recycling a few of the concepts for
Windstille.

Closely after Retriever came Vect, a simple vector graphics editor,
that might be used to create the graphics for Retriever. Its kind of
usable, but not exactly very confortable, it again was coded primary
for DOS with DJGPP and Allegro.

Then I moved onto Linux and switched from Allegro to ClanLib, my first
game then happens to be Pingus, a rather straight forward Lemmings clone with penguins, its
quite playable, but to this day not exactly finished.

Sometimes after that I did a tiny little bit work on TuxRacer, nothing
big, just a script for Gimp to make level creation a bit easier, a few
levels and a few bug reports.

The next game that I wrote from scratch was Feuerkraft, it was
somewhat inspired by the old Amiga game Firepower, but not a direct
clone, it has plenty of influence from games such as GTA and Operation
Flashpoint, as with most of my stuff, I never really finished it.

Sometimes in between I did start Advent, which was basically a rewrite
from Retriever. I was trying to give it a proper scripting interface
and make it properly extensible, which Retriever really wasn't. One of
the results was Cosmos, a little demo game build on top of the engine,
due to library and binary incompatibilities it however might no longer
be playable today:

Then came Freecraft aka Stratagus, a real time strategy engine along
the lines of Warcraft2. Its again a project where I didn't really
contribute much and only joined in rather late. For most part I simply
organize the rename from Freecraft to Stratagus that was needed after
the cease and desist letter from Blizzard, I picked up the bits and
pieces, did a new webpage and some stuff like that. I didn't ever
touch the engine itself.

In the follow up of the Stratagus rename came Robovasion, it was meant
as a little demo game to show that Stratagus can be used for other
games beside Warcraft2. While the basic design got quite finished, it
never got properly implemented due to some missing core features in
Stratagus. Since in the meantime there followed other games that made
use of Stratagus as an engine there soon was no longer a need for
Robovasion, so it never got finished.

Construo is again a project I started myself and did most of the
coding. Its a simple particle+spring engine/editor, the game doesn't
have any goals, its more like LEGO bricks where you can just toy
around with and build your own stuff. Its one of the few games I did
that ever become fully playable, its not 100% feature complete, but
what it does, it does quite well:

Sometime after that came Windstille, it started as a little recreation
of Turrican style gameplay, but soon moved on to became something very
different. A little demo with Turrican style gameplay was however
released:

Windstille on video.google.com

netPanzer was kind of interesting, one day I got a email of one of the
original creators who asked me if I had some use for the code in
Feuerkraft, since Feuerkraft was a 2D action game, not a stratagey one
I declined. Since the netPanzer project didn't went anyway after a
year I contacted them again if they still want to do anything with the
code, they agreed that it would be ok to OpenSource it and so I build
a little webpage and announced it on happypenguin.org. Soon after the
announcement was done some people picked it up and ported it to Linux,
I again didn't really touch much of the code, but simply did a bit
organisation here and there.

A while after that Happypenguin GoTM was born, it was a project meant
to pick every month a open source game and improve some key aspects
of it. We started with SuperTux and joined an already ongoing effort
to bring the old SuperTux into a clean shape. I did most of the
graphics, some code and around half of the levels of the reborn
SuperTux Milestone1.

After SuperTux was done, some people moved on to TuxKart, we didn't
manage to turn it into a playable game and had to fork it due to some
issues, but plenty of new graphics got done and some unfinished
improvements where done. A while after the SuperTuxKart code was
picked up by some other people and the project is quite alive know
gain:

Then GotM picked LinCity and we gave that game some new graphics and
user interface, I modeled most of the 3D buildings, while other people
worked on the code and interface graphics. The project got mostly
finished, however I still consider it a failure since one of the key
problems wasn't addressed, namely the game still misses a proper
tutorial and some game elements just don't make any sense.

Windstille also got picked up by GotM, while we didn't manage a
release, it got a large over vault and its the game that I am
currently still working on. Beside from that I am also a little bit
working on getting SuperTux Milestone2 done.

Q. Of the above, do you have a favourite?

Construo is probably my best game that nobody knows about, its plain
and simple and actually fun to play, while many of the other projects
never went that far and got stuck somewhere earlier. It happens to be
the only of my games that I can actually enjoy playing. Beside from
that there is also Windstille, since that game is in some part based
on Retriever and I am kind of working on it for like 10 years I have
grown pretty attached to it.

Q. What attracted you to developing & contributing to open source
games rather than selling your efforts as shareware or commercial
titles?

Rather simple: Money means trouble, no money means a smooth ride. If I
open source it I don't have to care about advertising, publishers and
whatever, I can simply concentrate on the game and do whatever I like
instead of trying to figure out what would actually sell. Open Source
also gives the freedom to recycle bits and pieces from other project
much easier. Its also much easier to accept contributions when no
money is involved.

That said, all this is of course only true as long as you don't need
the money and do it in your spare time, when you actually want to make
a living out of writing games Open Source doesn't seem to be much of a
good choice.

Q. From your experiences, what would you say are the best tips for
making a successful open source game?

I think the by far two most important things are this:

Figure out what exactly you want to do before announcing the game to
the public. Sounds simple, but many Open Source games completly fail
on that, people tweak around an engine for month and years without
anybody having a clue where the whole game is actually going. So they
never really go anywhere with their project, but just running around
in circles forever.

Don't expect anybody else to help you, be prepared to do everything
yourself. When you do a Open Source game you won't magically get
contributions, you might get none at all, so you shouldn't depend on
them to get the job done, but instead be prepared to do everything
yourself.

Q. What are the things to avoid, the things that make FLOSS game
development fail?

One simple rule would be to not start a new project, ever. Try to join
one of the already ongoing Open Source projects, if you don't see them
going anywhere, hijack them and give them some direction. A goalless
project can often be very easily turned into a different direction, it
just requires that you actually know exactly where you want to be
going.

Another thing: Don't aim to low. Of course you shouldn't try to do
Doom3 when you don't have a clue about 3D programming, but there
simply isn't a need for yet another Tetris clone, we have by far
enough of that. If you try something new, try to actually make
something new, don't just recreate something for which there already
exist dozens of recreations.

Q. If you could take one abandoned FLOSS game and restore it's
development (excluding your own titles!) which would it be?

Liquidwar, that game has a pretty cool concept, but rather ugly
interface and graphics, it could definitvly need some additional
polish and improvements.

My favorite Adonthell also needs a new release, it has been going
forward very slowly in the last years and could definitvly need a
solid push.

Q. What are your future game development plans and which of your
games do you hope to see come to fruition in the near future?

I currently do a lot of work on Windstille, a lot of which actually
isn't even very relevant to the game itself (i.e. history, ship
design, etc.). I am more or less trying to create a little universe
instead of just what I would need for a simple 2D action adventure.
If I ever get done with Windstille itself, I probably turn some of
that additional material into a game of its own. One thing I always
wanted to do was a realistic mech simulation, kind of an Operation
Flashpoint in space type of game. However knowing that such a game
would require a loooonnnggg time I prefer to stick for the moment with
my simple 2D game in the Windstille universe, since even that is
already hard enough of a thing to get done.
